A couple of issues with XP

I have a couple of issues with XP right now and I have no idea on how to fix them.

1. Whenever I open my computer and try to look at my drives a searchlight keeps on moving around and it never finds my folders. Ive already done the tip where I have to un-check automatically look for folders but still no results.

2. When ever i look in folders to open images all images load slow and not to full resolution in the thumbnail. They always show up really small and pixelated and all folders that I try to open them with load slow as well.
